HydraLux-4 is First Liquid Cooled LED Lightbulb

While those of us trying to save on our energy bill are using CCFL lightbulbs, the real future of efficient lighting is in light emitting diodes, or LEDs.

Los Angeles-based Eternaleds just unveiled its latest LED bulb product, the HydraLux-4 which uses just 4W to give off the light equivalent of a 25W incandescent bulb. What really sets the HydraLux-4 apart is that it's liquid cooled – a world's first.

"Most other LED globe shaped bulbs use metal or fans to surround the bulbs to keep the components inside cool. This design only allows light to come out of the top half of the bulb, like a spotlight." explains Jeff Chan, founder of Eternaleds, Inc. "This is the first LED light bulb to give true 360 degree light and really opens up applications that people can replace with LED lighting."

Eternaleds claims that the HydraLux-4 is a better 'green' solution than CCFL bulbs for chandeliers, sconces and decorative lamps.

The Eternaleds HydraLux-4 comes in two colors, Warm White and Daylight White, and can be ordered directly from Eternaleds.com at a list price of $34.99. It's an expensive investment, but it's rated for 35,000 hours; and at 8 hours a day, the HydraLux-4 costs around $1.75 per year to run, saving an average of $157.00 over the lifetime of the bulb in electricity and bulb replacement costs.

Eternaleds plans to announce 8W, 12W and 16W versions of the HydraLux by the end of 2009.
